Why did GOD allow Chrsit to die by Crucifixion ?

I think theologians have contemplated this question for ages. Why would not our loving Father save Christ from this most terrible fate?

I can barely stand to think of the crucifixion myself. This age was so horrible, crucifixion and impaling was the most extreme punishment for crimes. Why would a prophet or the son of God ever earn such a sentence. Rome was the most brutal of empires giving birth to some of the most evil leaders and rulers whom were referred to Draconian.  Domitian, Septimius Severus, Maximinus Thrax,  Diocletian,  Tiberius, Nero, Caracalla, Commodus,  Elagabalus and Caligula.

When Jesus was born (approximately 5 BC) the Roman emperor was Gaius Julius Caesar Augustus who reigned until 14 AD. At the time of crucifixion and death (approximately 30 AD) the Roman emperor was Tiberius Julius Caesar Augustus who reigned until 37 AD. The Roman emperors would have most likely worshiped pagan gods. Roman religion was a mix of various religious traditions from places such as Greece and Egypt. Mystery religions dedicated to various deities were also popular in the Empire at the time of Jesus.

The Roman empire was in the first few centuries AD expansionist and in its conquests accommodated new cults and philosophies from different cultures, such as the Persian cult of Mithraism, the Egyptian cult of Isis and Neo-Platonism, a Greek philosophical religion.
Paganism was never, then, a unified, single religion, but a fluid and amorphous collection. But it would also be a mistake to describe Roman religion as an easy, tolerant co-existence of cults. ‘Toleration’ is a distinctly modern, secular idea. The emperor Constantine converted the main religion of Rome to Christianity in, or about, 312 AD.

His understanding of Christianity was, at the stage of his conversion, unsophisticated. He may not have understood the implications of converting to a religion which expected its members to devote themselves exclusively to it.
However, what was certainly established by the early fourth century was the phenomenon of an emperor adopting and favoring a particular cult. What was different about Constantine’s ‘conversion’ was merely the particular cult to which he turned – the Christ-cult – where previous emperors had sought the support of pagan gods and heroes from Jove to Hercules.

Given the timeline of events and occurrences on can see the pattern emerge, though time itself played a role. The persecution and crucifixion of Christ and a grand scale purpose in illuminating the wickedness of Rome and their Rulers and their religious practices.  Illuminating the corruption of the Jewish High Priest (Pharisees).

This is why Christ received the most brutal of sentences, moving away from mainstream explanations "by the blood of Christ" we are healed. By the blood of Christ the world changed. The execution and death of Christ was the very path which the main Christian faith and church rose from, which lead to its dominance world wide.
